high-resolution

问题 In Firefox I can create a fullpage screenshot when I go to the web developer toolbar (can be activated in the developer tool settings). Unfortunately, I can do this only with the default resolution. Is there a chance to get images of higher resolution anyhow? With Firefox or an add-on? Or is it possible in another browser? 回答1: Firefox 62 and following In Firefox 62 and following, the GCLI was removed and the screenshot command was moved to the Web Console and prefixed with a colon.

问题 I'm processing images when the user uploads a pic but my problem is high rez pics. How do you detect when the user uploads one? I'm using the GD library for PHP. Setting the quality to 90 with the imagejpeg() method doesn't do anything to it but scales the dimension and then sets the ppi to 72. I want to be able to preserve the dimension and drop the ppi to 72 at the same time. Any advice would be greatly appreciated. 回答1: There is no such thing as PPI as far as you need to be concerned. Also

问题 I need to get exact timestamps every couple of ms (20, 30, 40ms) over a long period of time (a couple of hours). The function in which the timestamp is taken is invoked as a callback by a 3rd-party library. Using GetSystemTime() one can get the correct system timestamp but only with milliseconds accuracy, which is not precise enough for me. Using QueryPerformanceTimer() yields more accurate timestamps but is not synchronous to the system timestamp over a long period of time (see http://msdn

问题 I'm looking for help with the programming language/environment Processing. I'm fairly new to Processing and I am experimenting with a piece of code from someone over at openprocessing.org. I really like the visual results this code delivers and I would like to further work with it. Unfortunately, the output is very low resolution. Hence I'm looking for someone who might be able to help me figure out how to a) Increase the size or resolution of the shapes generated and b) save everything as a

问题 I'm using this example project's XNA 4.0 form control in an application I'm writing: http://creators.xna.com/en-US/sample/winforms_series1 It's working great and I've done quite a bit with visuals and animation. The main issue I'm scratching my head at is the 3d model and primitive 3D shapes (cylinders with a tessellation of 30) I render have very jagged edges to them as if they are low resolution. I tried to figure out how to enable multisampling, but all of the examples I can find online

问题 I just want to open native camera app from my app to capture a photo and set it as a background image of my screen then rotate it onclick of button. Photo is rotating n number of times if it is taken with 3MP camera. If i set camera resolution to 5MP or more, app is force closing on click of button 5th time (photo is rotating 4 times) . Bitmap rotatedBitmap = null; int curAngle = 0; private Bitmap rotateImageBitmap(Bitmap capturedPhotoBitmap) { if(rotatedBitmap != null ) { rotatedBitmap =

问题 I want to get a snapshot of my webgl canvas and I want a high resolution capture so I increased my canvas size. This automatically changes gl.draingBufferWidth and gl.draingBufferWidth . I then set viewport and then render the scene. My code works correctly in low resolution (under 4000*4000) but in higher resolutions there are many problems. If the resolution is a bit higher the snapshot not does not completely show. See attached file. If the resolution increases more nothing is shown. And

问题 I'm trying to emulate Xcode's toolbar controls to show/hide the Navigator and Inspector: ...but without the bottom pane (only left and right: two segments) I screen-captured the icons from Xcode's UI and traced them in an image editing application. The resources for the left pane are: @1x: (20x20 @72 dpi) @2x: (40x40 @72 dpi, although using 20x20 @144 dpi seems to make no difference) The right-pane counterparts are identical, but flipped horizontally. All rhe resources are stored in the asset

问题 I'm writing a kernel module that requires function called in 0.1ms intervals measured with at least 0.01ms precision. 250MHz ARM CPU, the HZ variable (jiffies per second) is 100 so anything jiffies-based is a no-go unless I can increase jiffies granularity. Any suggestions where/how to look? 回答1: Assuming the kernel you are running has the Hi-Res timer support turned on (it is a build time config option) and that you have a proper timer hardware which can provide the needed support to raise
